Homogeneous Immunoassays: Historical Perspective and Future PromiseEdwin F. UllmanThe founding and growth of Syva Company is examined in the context of its leadership role in the development of homogeneous immunoassays. The simple mix and read protocols of these methods offer advantages in routine analytical and clinical applications. Ullman, Edwin F. J. Chem. Educ.1999, 76, 781.

The Sweetness of Aspartame: A Biochemistry Lab for Health Science Chemistry CoursesPaul J. SteinA laboratory exercise to study the effect of aspartame concentration on sweetness has been developed. Class data is averaged and plotted on the same graph as absorbance and taste rating vs. [aspartame]. The absorbance plot follows Beer's law while the taste rating plot displays the hyperbolic response of protein-ligand binding plots.Stein, Paul J. J. Chem. Educ.1997, 74, 1112.
